摘要
介绍了旧桥承载能力分析评估方法。以预应力混凝土连续刚构箱型截面旧桥(跨径85m+150m×3+85m)为研究背景,在外观检查的基础上,确定了该旧桥的技术状态等级和旧桥结构检算的各项系数,用有限元软件Midas Civil进行了结构分析建模,并进行了桥梁结构承载能力极限状态与正常使用极限状态下的检算。结果表明,该桥满足正常运营承载能力的要求。
The process of carrying capacity analysis and evaluation for the bridge are introduced in this paper.Taking an old prestressed concrete bridge with span of（85＋150×3＋85）m as an example,the checking coefficient and technical state level are determined on the basis of the exterior inspection.Midas Civil finite element software is used to model and check the capacity under the bearing capacity limit state and the normal use limit state for each unit.The calculation results show that the bridge meets the requirements of the normal operation carrying capacity.
